I Specification of Letters Patent.

Application filed November 27, 1908. Serial No. 464,663.

To all whom it may concern: M

Be it known that I, LEO F. Aer, of Al- 7 bany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Eyeglasses; and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of the specification, and to the reference-numerals marked thereon.

The present invent-ion relates to eyeglasses of the type embodying nose guards mounted to swing substantially in a horizontal plane and each having a forwardly extending operating portion and a rearher that the latter may be removed without sists in certain improvements and combinations of parts all as will be hereinafter morefully described, the novel featuresbeing pointed out in the claims at the end of the specification. In the drawingsz'Figure 1 is an enlarged top view of the mounting and portions of thelenses. Fig. 2 is an enlarged front view. Fig. 3 is a central vertical section. Fig. 4 is a-perspective view ofone of the guards. Fig. 5 is a detail view to illustrate the manner of removing the spring, and Fig. 6 is a detail view to illustrate the cooperation of the projection with the support to prevent a guard riding over the bridging portion.

In the present embodiment ofthe invention, the lenses A are carried by a support which preferably comprises a bridging portion 1 connected to the lens attaching devices 2 by horizontal seats 3. The nose guards in this instance are mounted to swing on the seats 3 substantially in a horizontal plane and for this purpose the seats may have pivots 4 projecting upwardly therefrom ,to cooperate with earings on "the guards, the upper end of the pivots being provided with heads to prevent vertical movement of "the guards. The bearings 5 ion the 'guards preferably are, provided in ithe levers (i/and open horizontally toward the lens attaching devices sothat the springs ifor' positioning the guards may be carried bythe latter'and operate beneath the 'sup fiport without interfering with the lens-at- ;taching devices when the guards are re: grooved, the spring during the removal pass- {111g beneath the arched bridging portion in ;order to permit the-guard lever :6 to be tilted. 1 I

In the present embodiment each spring is in. the form of a coil 7 and. an arm 8. The coil is preferably of volute form with its axis vertically arranged, and its inner end connected to the rear-end of a lever 6 and its outer end connected to arm 8 that projects forwardly; and cooperates with the support to slide thereon and exerta pressure on a guard inorder to retain its hearing 5 in cooperative relation with a pivot 4c. The point 9 on which: the arm slides may be in the form of a bracket or hook depending from the support, and located between the pivots 4t and in advance of the latter. This location of the points 9 permits the arms 8 to be given maximum lengths and causes the latter to slide on the points in directions to increase their elfective lengths, thus tending to ease the actions of the springs toward the last part of the opening movements of the guards and while'they are under greatest tension. i V

The nose-engaging portions of the guards may be in the form of nose-engaging members eachhaving an upper pad l'() and a lower pad '11 with an arm 12- branched there; from and secured to a lever 6 which for this purpose may have a vertically offset portion 13 preferably in the form of an upwardly extending loop to one arm of which, one end of a coil 7 may be connected, the arm 12 of a nose-engaging member being secured between the arms of a loop.

The specific construction and arrangement PatentedQctJ, 1912 application, Serial No. 479,809, filed by me February 24, 1909.

In order to prevent the le'verriding on the bridging portion each lever maybe pro-" vided with a projection 14 on its side adjacent the bridging portion, and this projection will near the last part of the opening movement pass beneath and engage the under side of the upwardly curved bridge.

t is desirable for the purpose of eliminating fastening devices which would increase the size of the mounting, that the lever G,

' coil 7 and arm 8 be formed from one piece of'flat stock, and tothis end a blank is pro' vidd and twisted nearone end to form; a

fingerpieceor operating portion for the guard. Inrear of the bearing recess the blank is bent transversely o the flat faces to form the loop 13 one arm of which is carcoils are located directlyin rear of the supried downwardly and twisted at 15 and then bent transversely otthe fiat faces to 'form the horizontal volute coil, the outer end ofthe coil having the arm 8 proceeding from one side edge thereof and formed by a bend transverse ot the fiat faces of the stock.

. The guards-are operated by pressing the forwardly extending operating portions together, thus causing their nose-engaging portions to separate, the springs acting to move the latter together when the guards are released/ITO remove-the guards from the mounting 'fOI the purpose of fitting the eyeglasses the v arms 8, are disengaged from hooks9 and spring beneath the bridging portion to permit the guards to be turned without interference with the support. The

port so thatthey are invisible when the mountingis viewed from the frontand the spring arms, bear on the support in such a manner that the action of the guards is not hard near the end of their opening movej ments.
